the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

1. A freezing tray including flexible walls and a bottom, the bottom being disconnected from the wallsat the front of the tray, and means reinforcing the walls and the bottom at localized portions thereof to permit the front of the tray being rocked downward below the bottom.

2. A rubber freezing tray including walls and a bottom, means reinforcing the walls to a point adjacent the front of the tray, means reinforcing the bottom at the marginal edge thereof, a rubber sub-bottom connecting the walls at the front of the tray below the bottom and hinged to the bottom, and means connected to the front portion of the tray by means of which the front From the above description is is thought that.

portion and sub-bottom may be deformed downwardly below the bottom of the tray.

3. The combination with the bottom or a freezing box, of stops on said bottom, a rubber freez v ing tray having the front portion deformable below the bottom of the tray and below said bot tom of the freezing box, and stops on the tray 7 to the rear end of the rod for effectively lossening and dislodging ice cubes when the rod is pulled forwardly.
